Abaqus has no units built into it except for rotation and angle measures. Therefore, the units chosen must be self-consistent, which means that derived units of the chosen system can be expressed in terms of the fundamental units without conversion factors.
You need to check that the values used make up a consistent set of units.
Symbols used in Abaqus for units
Some typical consistent set of units are shown in the table below:
Units: N,mm
Length = mm
Force = N
Mass = Tonne (1.0E3kg)
stress = MPa (N/mm^2)
Time = s
__________
E of steel = 207000 (MPa)
Yield = 450 (MPa)
gav = 9807 (mm/s^2)
Density = 7850 kg/m^3 = 7.85e-9(ton/mm^3)
